XML as parameter to WebService(Resolved)

[rjv_rnjn]

Hi all,
I've made a web service in VB.Net which can read an XML file at a predefined location and take the required action. What I am interested in knowing is: Can I pass the XML document itself to the web service?
To make myself very clear I will detail a bit more here;

WebService:
Public Function FuncA(XML document) : Calls a private function which processes the XML data.

Client App:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim test As New localhost.ExampleWebService
        test.FuncA(XMLObject)
End Sub

I think this makes clear what I want to achieve. If any further clarifications are required please let me know.
Thanks.
